The-bolt is preferably of slightly lesserdiamthe Structure in the manner hereinabove deeter than the openingsI'I, I8 and I9 in the plates 55 scribed at spaced intervals therealong,leaving,

for example, four or iive holes open between each clamp for theinsertion of rivets. The clamps should be suiciently closely spaced,however, to prevent the plates and angles from separating inasmuch as itis very important that these members be maintained in a mutually tightpressed relation for the riveting operation.

If the holes in the angle are punched close enough to the flange I2thereof, the end of the oiset portion 22 of the bolt 3l) will engage thesame to prevent rotation of the bolt when the Wing nut 23 is beingrotated into engagement with the outer plate. I

It may thus be seen that the clamps may be applied from a positionexteriorly of the structure, and that but one man can easily andexpeditiously perform this operation. After rivets have been inserted inthe open holes of the structure, the clamps are removed and rivets maythen be inserted in the holes thus provided to complete the operation ofriveting the plates to the angle framework.

It is to be understood that the form oi our invention, herewith shownand described, is to be taken as a preferred example of the same, andthat various changes in the size, shape and arrangement of parts, may beresorted to without departing from the spirit of our invention, or scopeof the appended claims.

Having thus described our invention, we claim:

1. A riveting clamp comprising abutment means adaptable to be insertedthrough an opening, a threaded portion above said abutment portion, amanually operable nut engaging said threaded portion, and a finger pieceabove and offset from said threaded portion.

2. A riveting clamp comprising a threaded portion, abutment meansadaptable to be inserted through an opening, said abutment being anoblique extension of said threaded portion, a manually operable nutengaging said threaded portion, and a iinger piece above and offset fromsaid threaded portion.

3. A riveting clamp comprising abutment means adaptable to be insertedthrough an opening, a threaded portion above said abutment portion, amanually operable nut engaging said Cil threaded portion, said nut beinga wing nut, and a nger piece above and offset from said threadedportion. i

4. A riveting clamp comprising a threaded portion, abutment meansadaptable to be inserted through an opening, said abutment being anoblique extension of said threaded portion, a manually operable nutengaging said threaded portion, said nut being a wing nut, and a fingerpiece above and oiset from said threaded portion.

5. A riveting clamp comprising abutment means adaptable to be insertedthrough an opening, a threaded portion above said abutment portion, amanually operable nut engaging said threaded portion, and a finger pieceabove and offset from said threaded portion, said finger piece being anangularly projecting upper extension of said threaded portion.

6. A riveting clamp comprising a threaded portion, abutment meansadaptable to be inserted through an opening, said abutment being anoblique extension of said threaded portion, a manually operable nutengaging said threaded portion, and a finger piece above and oiset fromsaid threaded portion, said nger piece being an angularly projectingupper extension of said threaded portion.

7. A riveting clamp comprising abutment means adaptable to be insertedthrough an opening, a threaded portion above said abutment portion, amanually operable nut engaging said threaded portion, said nut being awing nut, and a finger piece above and oiset from said thread- Vedportion, said iinger piece being an angularly projecting upper extensionof said threaded portion.

8. A riveting clamp Comprising a threaded por tion, abutment meansadaptable to be inserted through an opening, said abutment being anoblique extension of said threaded portion, a manually operable nutengaging said threaded portion, said nut being a Wing nut, and a ngerpiece above and oifset from said threaded portion, said linger piecebeing an angularly projecting upper extension of said threaded portion.
